tableprint's Issues

No width validation

When adding data that is wider than the tty screen, the table just breaks.

Auto-width

Love tableprint!

Since everything is monospaced, it should be easy to set the width on each column automatically based on the longest string value of each column (and its header). Could you please implement this? It would save precious horizontal space and fit more columns.

Feature request: Horizontal alignment

This is a simple, lightweight, and awesome package and exactly what I needed to print some database data in my CLI app. Any chance you could add two parameters for horizontal alignment that takes a string for the alignment of the cell data, such as "left", "center", or "right"? Something like header_align and row_align?? As it is right now I have to pad all the strings to be the same length as the longest one otherwise the table is difficult to read.

Thanks so much!

Simple style csv or json or yaml

It would be pretty handy to have a style option to simply print csv, json, yaml formatted output

Drop Numpy as a hard requirement

Including Numpy as a necessary requirement is extremely heavy for a terminal printer. It seems like you just use it to convert a dataframe to an array and to do a floor function on a scalar(!). The latter can be easily replicated through math.floor in the stdlib, and for the former, you could attempt to import Numpy if it exists inside the dataframe function (if someone's giving you a Pandas dataframe you know there'll be Numpy).

feature request: print multiple items in a column (group by)

Something like:

-------------------------------
| A               | B1                   |
|                   |  B2                  |
|                   |   B3                 | 
--------------------------------

if A elements are the same, but B1 & B2 elements are different.
(in fact, table is a result of a "group by column 1" )
I can try to simulate this by inserting rows with zero value for column A, but i don't know that order will be kept.

Irregular Table Width

I tried to use this module in my script, But got irregular table width.

Can you help on this?

Custom print command

It'd be useful if tableprint could accept a custom print command. In my use case, I want to progressively (print-as-I-go) print the values of TensorFlow 2 tensors in a table.

In autograph, the only way to print TensorFlow tensors is with tf.print—using print(my_tensor) doesn't print the value.

I can think of two ways to approach this:

• accept a callable that defaults to Python's print.
  • The only problem is that there are certain options that tableprint may need to pass to tf.print; for example, output_stream. Since these arguments differ from those of Python's print, tableprint's implementation will need to use if statements to see if the callable is tf.print. This brings me to the second option:
• accept a boolean called print_tensorflow that defaults to False. If True, print using tf.print.
  • I like this idea better since the first option implies that any callable can be used, such as click.echo, even if tableprint doesn't have click.echo's options implemented (of course, a NotImplementedError could be raised).
  • However, this would limit tableprint to only print and tf.print. If you want to add more callables in the future, you could always change this argument to a string, and use an if statement to see if the string is python, tensorflow, click, etc.

str(array) is not stable for table print

ANSI escape not supported

The column size is improperly computed with the following example:

import tableprint as tp
from numpy.random import randn
from termcolor import colored

tp.table(randn(2,1), [colored('Foo', 'red')], style='fancy_grid')

It gives:

╒═══════════╕
│Foo│
╞═══════════╡
│  -0.060884│
│     -1.034│
╘═══════════╛

I think this can be corrected on header by using this:

    def format_headers(string):
        s = max(width - _ansi_len(string), 0)
        return (' ' * (s / 2)) + string + (' ' * (s - (s / 2))) if s else string

    data = map(format_headers, headers)  

Also the _ansi_len should be rewritten:

def _ansi_len(string):
    """Extra length due to any ANSI sequences in the string."""
    return len(re.sub(r'\x1b\[([0-9,A-Z]{1,2}(;[0-9]{1,2})?(;[0-9]{3})?)?[m|K]?', '', string))
